Nice, welcome to the site!
Okay thanks for the info, im going to check out ebay and see what kind of parts i can spring up, any good parts companys that i can look up?? theres a lot of snow outside so im in no hurry to build it, i want to do it right the first time rather than just drive it and blow it upThe 54cc is still a 44mm bore just like 49cc Cag engine, it probably has 5 ports like my blue winged head avatar photo engine. If you have a 47cc, that is 43cc w/ a 40mm bore. I would look on e-bay for a 49cc head kit with 4pc head with cyld & piston & stuff, FC crank, rocket key. Get some new crank bearings an seals and build your own for less than $100. My blue head kit w/ FC crank and all $74.99 shipping direct from Hong Kong air mail. I seen $160 FC crank HP engines on eBay, you still need to go over the whole engine and up your compression or Squish to get real power. Welcome to the nightmare,lol.
